Abstract :
The influence of 3-3.7-MeV proton bombardment in vacuum media on superconducting properties of Y-Ba-Cu-O films obtained with the aid of pulsed laser deposition on SrTiO3 substrates is investigated. It is shown that in the samples investigated Tc drops linearly with increasing irradiation dose, the rate of this drop is approximately five times quicker than for Nb3Sn and there also takes place a broadening of the superconducting transition
